Arkadaşlar Nucleo-F767ZI kartımda one-wire ile ilgili sorun yaşıyorum. Amacım DS18B20 sıcaklık sensörlerinden veri okumak. Sorun ise cihaza ilk enerji verildiğinde, program Read_Rom() fonksiyonunda kilitleniyor. İşin garibi eğer ise derleyici ile 1 kez program yükleme yapıldıktan sonra hatasız çalışıyor. Sadece ilk enerji verildiğinde kilitleniyor, reset butonu ile reset atsam bile düzelmiyor. Bu sorun nereden kaynaklanıyor?

F4 discovery ve nucleo-F401 kartlarda aynı yazılımı denedim. Böyle bir sorun oluşmadı. Denetleyicinin bir ayarından dolayı oluyor sanırım.
